Uses For amlodipine, valsartan, and hydrochlorothiazide
Amlodipine, valsartan, and hydrochlorothiazide is a combination of medicines that is used to treat high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a heart failure or kidney failure. Lowering blood pressure can reduce the risk of strokes and heart attacks.
Amlodipine is a calcium channel blocker (CCB). It affects the movement of calcium into the cells of the heart and blood vessels. As a result, amlodipine relaxes the blood vessels and increases the supply of blood and oxygen to the heart while reducing its workload.
Valsartan is an angiotensin II receptor blocker (ARB). It works by blocking a substance in the body that causes the blood vessels to tighten. As a result, valsartan relaxes the blood vessels. This lowers blood pressure and increases the supply of blood and oxygen to the heart.
Hydrochlorothiazide is a thiazide diuretic (water pill). It reduces the amount of water in the body by increasing the flow of urine, which helps lower the blood pressure.
amlodipine, valsartan, and hydrochlorothiazide is available only with your doctor's prescription.
